help! Accidentally sold my premium item trying to place it in cafe

Hello! I’m trying to reach someone at the company. I just bought part of the premium sushi stand that gave me more XP with 96 of my silver likes. I tried to place it in my café and somehow hit the sell button. Can someone help undo this please!!! Why is there a sell button on premium items like this. All those hours of hard work gone for my 96 silver 😭😭😭
